To determine whether the crown was made of pure gold or not, we need to compare the density of gold (19.3 g/mL) to the density of the crown.
The formula for density is
we know the mass of the crown is 714 grams and its volume is 38.3 mL. (Because it displaces 38.3 mL of water)
Using this information, we can plug the numbers into our density formula to solve for the density of the crown.
The density of the crown is 18.6 g/mL, thus the crown was not made of pure gold, as that has a density of 19.3 g/mL. In conclusion, the goldsmith tried to screw over the king.
The best and the correct answer among the choices provided by the question is the second choice or letter B.

A molecule is multiple atoms put together so an atom will always be smaller
Use the Keq equation.. concentraion of products divided by concentration of reactants at equilibrium. (with coefficients as exponents, none in this case reaction is balanced)
Keq = [PCl5] / ([PCl3] [Cl2])
fill in given values and solve for [Cl2] using algebra. Im just going to sub in "c" for the unknown.
0.00094 = 0.44 / 0.33c
0.0003102c = 0.44
c = 1418.44 mol/L
